The Yellowstone County Museum will be under construction from April to September 2025. We are committed to staying open as much as possible during construction. However, for public safety, there may be occasional closures.

The Museum will be closed from April 15th to April 26th for asbestos abatement as part of our ongoing facilities upgrade. We will open again on April 29th.

The facilities upgrade will include adding a new entrance, stairs, wheelchair lift to the lower-level, and bathrooms. The historic Paul McCormick Cabin will become a display room dedicated to the early history of the area. The upgrade will also provide the first indoor space the YCM has had for educational programing during open hours.
